After working out, drinking a special protein and sugar shake helps your muscles start building more efficiently by turning on key signals inside your muscle cells, better than just working out alone.

Consuming a specific combination of amino acids and carbohydrates one hour after a resistance workout in young, untrained men leads to a measurable increase in muscle protein synthesis and activation of key signaling proteins involved in protein production, compared to performing the workout without this nutritional intake.

If young men who don’t usually lift weights drink a special protein-and-sugar shake one hour after working out, their muscles build protein much faster—nearly triple the rate—than if they just worked out alone, probably because the shake turns on key muscle-building signals in their cells.

After resistance training, consuming a drink containing leucine-enriched amino acids and carbohydrates leads to a measurable increase in a specific molecular marker linked to the start of muscle protein synthesis, compared to training without the drink.

In young, healthy men who exercise recreationally, consuming leucine is linked to specific molecular changes in muscle cells that are thought to support increased muscle protein synthesis.
